UI anthropologist, colleagues discover remains of earliest giant panda

... Chinese Academy of Sciences, shows that the basic anatomy of the giant panda has remained largely unchanged for millions of years. Ciochon says that the skull --, about one-half the size of a modern-day giant panda skull, but anatomically very similar -- indicates that the giant panda has evolved for mor...

Lithium builds gray matter in bipolar brains, UCLA study shows
